This paper considers the performance evaluation of multimode diversity antennas with spatially orthogonal radiation patterns in UWB indoor communications. Since the wave propagation in UWB indoor communications is subject to severe spatial dispersion leading to large angular spreads in the angular power density spectrum, diversity antennas with spatially orthogonal patterns may provide important means to substantially enhance UWB wireless link conditions. We will focus on the system analysis of the MB-OFDM UWB link with multimode antennas in receive diversity operation. The multimode antenna patterns are modeled in terms of orthonormal spherical harmonics.
